SAFE-BOLTWORK.

Specification of Letters Patent.

Patented Dec. 30, 1913.

To all whom it may concern: 7

Be it known that I, CARL BARTELS, a c tizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements 1n Safe-Boltwork, of which the following is a specification.

This invention pertainlng to safe boltwork and relating particularly to the connection between the main bolts and the locks which guard them, will be readily understood from the following description taken in connection with theaccompanying drawings in which Figure 1 is a rear elevation of a safe door, shown for exemplifying purposes as of round. door type: Fig. 2, a partial radial section of the same, in the plane of line a of Fig. 1: Fig. 3 an elevation, on an enlarged scale, of the lock-work:F1g.4,a substantlally radial section through a portion of the door in the plane of line b of Figs. 1 and 3: and Fig. 5, -a transverse section through the time-lock plunger, in the plane of l ne 0 ()1. Fig. 3.

In the drawings :--1, indicates the rear surface of the door of a safe, the door being shown, for mere purposes of exemplification, of being of the round door type: 2, the outer bolt-ring projecting rearwardlv from the door: 3, the inner bolt-ring: 4, the bolts sliding in the bolt-rings: 5, a shank projecting inwardly from the inner end of each bolt: 6, a bearing-ring carried by the rear surface of the door: 7, an actuatingring turning in this bearing-ring and having a peripheral notch for each bolt: and 8, a circular series of crank-disks mounted on the rear of the door and having upon each two crank-pins one of which engages one of the peripheral notches in the actuating-ring and the other of which engages a notch 1n the shank of the appropriate bolt.

The parts thus far referred to are without distinctive peculiarity so far as the present invention is concerned and are shown merely to exemplify door-bolts with their operating mechanism. Without going into detail it is sufficient to say that Fig. 1 indicates the bolts in inward or drawn position. If, now, actuating-ring 7 be turned, in nonclockwise direction, it will cause the turning of all the crank-disks and the shooting of all the bolts. The turning of the actuatingring may be eifected by means of any suitrest of the crank-disks, whereby all of the bolts are shot. I cause the shot bolts .to be dogged by a pair of combination locks and, preferably, also by a time-lock.

Proceeding with the drawings :9, indicates one of the combination locks, of ordinary construction, secured to the rear of the door: 10, a similar combination lock, which I will herein refer to as the upper combination lock or as the second combination lock: 11, the usual bolts of the combination locks: 12, a dog-bar arranged to slide to and from the two combination locks and having its outer end secured to the bolt mechanism as, for instance, by taking hold of one of the crank-pins engaging the shank of a bolt so that the bolts cannot move inward unless the dog-bar is at liberty to move inward: 13, a pivot: 14, a bell-crank mounted on this pivot and having an arm lying substantially parallel with the inner face of the combination locks and having another arm projecting out toward the dogbar and. adapted to have its end cooperate with the inner end of the dog-bar, this arm of the bell-crank being the dogging arm:

15, the outer end of the dogging arm of the bell-crank, the same being normally above the inner end of the dog-bar but adapted, by the tilting of the bell-crank, to take position behind the inner end of the dog-bar when the dog-bar is in its outer position corresponding with the shot condition of the bolts: 16, a lever having its lower end pivoted to the bolt of the lower combination lock and having its upper end pivoted to the bolt of the upper combination lock: 17, a link connecting the middle of lever 16 with the upper arm of the bell-crank, the outer end of this link being adapted for connection with the bell-crank at either of two selective points radially distant from the axis of the bell-crank: 18, the time-lock, shown as being disposed upon the door between the two combination locks: 19, a plunger having its outer end pivoted to the upper arm of the bell-crank, its inner end slid- .tachment, and thus serving as means for the socket open so that the plunger may retreat, and adapted, when the time-lock is on duty, to block the socket so that the plunger may not retreat: 21, one of the selective pivotal points of attachment between the outer end of link 17 and the bellcrank; and 22, the other selective point of attachment between the outer end of the link and the bell-crank, the attachment at these two selective points being of conveniently changeable character, such as screws or studs which will readily permit of the outer end of the link being disconnected from one point of attachment with the bell-crank and connected with the other point of atadjusting the point of pivotal connection between the link and the dogging member to cause the dogging member to go to releasing position under the influence of either or both of the combination locks as may be desired.

It is the aim of the invention that, under full guard, the drawing of the bolts shall be prevented by the two combination locks and by the time'lock, if a time-lock be employed; that the bolts cannot be drawn till the time-lock if employed, goes off duty; that the bolts cannot then be drawn until both combination locks have been operated; and that, if desired, the mechanism may be so adjusted as to cause the bolts to be dominated by but a single one of the combination locks, in the absence of the employment of the time-lock.

Assume, now, that the bolts have been shot; that the bolts of both combination locks have been shot; that the result of this.

is that dog-bar 12 has moved outwardly and end 15 of the horizontal arm of the bellcrank has gone behind the inner end of the dog bar. It may be assumed further that the time-lock has gone on duty, putting block 20 behind the inner end of plunger 19. Under these conditions the main bolts cannot be drawn, as the abutting of the inner end of dog-bar 12 against end 15 of the bell-crank positively prevents it, and any strain toward an attempt to draw the main bolts will impose no strains upon the combination-locks or the time-lock as those strains will be met entirely by pivot 13 of the bell-crank. Now, assuming that the time-lock is off duty, as indicated in Fig. 3, under the conditions previously noted, combination-lock 10 may be operated, causing end 15 of the bell-crank to take position above the rear end of dog-bar 12, thus permitting the dog-bar to retreat and all the bolts to be drawn. Precisely the same action would obtain if, instead of operating combination lock 10, its bolt had been left in shot condition and the bolt of combination-lock 9 been drawn. In other words, ignoring the presence of the time-lock, the construction is suchg when link 17 is hitched to pivot 21, that either of the comwork. In such case the draw end of link 17 is to be disconnected from pivot 21 and connected to pivot 22. Under these changed conditions the drawing of the bolt of one of the combination locks will lift doggingarm 14 only partially from behind the inner end of the dog-bar, leaving the main bolts still dogged. But when the bolt of the.

other combination lock is drawn then the dogging arm of the bell-crank is lifted to complete undogging position and the main bolts may be drawn. And this applies regardless of which of the combination locks be operated first. The time-lock, when on duty, has its block 20 so elevated as to pro} 7 vent the bell-crank being moved to undog- I ging position, regardless of whether the link be connected to pivot 21 or 22..

I claim Safe bolt-work comprising, main boltwork, means for shooting and drawing the bolt-s thereof, a pivoted clogging-member serving toprevent the drawing of said bolts, apairof combination looks, a lever having each of its ends pivotally connected with the belt of one of the combination looks, a pivot carried by said lever intermediate of its length, a linkconnectin-g said pivotand engaging a pivot on the clogging-member, means for adjusting the point of pivotal connection between said link and the dog ging-member to cause the dogging-member to go to, releasing position under the influ ence of either or both of said combination looks as may be desired, a time-lock, and connections between the time-lock and the same dogging-member which is linked to said lever to prevent said dogging-member going to releasing position under the influence of either or both of the combination locks while the time-lock is on guard, combined substantially as set forth.
